After I can not upload to play store (error: You uploaded an APK that is not signed with the upload certificate. You must use the same certificate.)
I go to menu "App integrity" and download certificate "Upload key certificate" (upload_cert.der)
because google say: This is the public certificate for your private upload key. Use your upload key to sign each release so that Google knows that updates are from you. Use the certificate below to register your upload key with API providers.
Thankyou Erel
My apps already in play store, and now I need to update
but play store say: You uploaded an APK that is not signed with the upload certificate. You must use the same certificate.
I already have file sign.keystore before, but different fingerprint
even though during the previous update (August 2021), the upload was still successful
what is the solution so that I can upload to the play store again
